...I have successfully run as a persistent USB flash drive. And this is only because it come with it's own built in "Install to Flash Disk" utility.
I've messed with "Linux Mint", Debian, Ubuntu with various levels of success. If I did get it working, it wasn't very stable. Doing this by following step-by-step instructions or by using a tool like Universal-USB-Installer.
Being able to take your computing environment to any computer (that can boot from USB) is a very attractive alternative.
Keep up the good work! Looking forward to the next Knoppix with even more persistent USB options. It would be cool if it could run from USB and be no different then if it were running from hard drive.
Hi utu,
Let me start by saying I'm no Linux expert so it's a good chance I don't know what I'm talking about.
With the other Linux distros (that didn't quite work out) I've had to specify all the different partitions. One for root "/", one for home "/home" and a swap partition. I'm assuming root is the only place additional software is installed and home is where my files go. The Knoppix USB persistent install is all on one partition with a max of 4 gig persistent space.
I may just be noticing the difference and assuming the other partitions are needed.
Having said all that, what I really would like to do is allocate the remaining space on my USB flash drive for persistent memory. I have a 16 gig flash drive and the highest I can allow for a persistent file is 4 gigs. I say this with the assumption that additional software is installed in the persistent area.
Thanks you for your time!
I'm also making the assumption the files I create are also stored in the persistent area. Now that I think of it, I'm not sure they would need to be.
Greetings again, Howie
With Knoppix 7.0.5 you have TWO choices for persistence files.
One choice is to create one within the same partition as the OS
using Fat32. This persistence file is not limited itself to 4 Gb, but files
placed on it must be less than 4 Gb. And the time it takes to
format a Fat32 persistence file is proportional to its size.
Formatting one larger than 4 Gb may make you think something's
gone haywire before it completes.
A new choice has been added which allows persistence to be
achieved with a separate reiserfs partition. This approach has
no similar 4 Gb file size limitation, and doesn't take any
time at all formatting.
There are a lot of good things about Knoppix and its LiveUSB
is my favorite choice of Linux.
Hello again, howie.
The reisers approach is the new 'experimental' approach.
I didn't have any problem with it, myself.
I started with an 8 Gb SanDisk cruzer and/or a 16 Gb SanDisk
'camera card'. Both were formatted Fat32, single partition
at the factory.
Some users report usbs pre-formatted with several small partitions.
That may be a problem. By the way, don't provide the reiserf partition yourself,
let Knoppix do it.
I suggest you see what your usb looks like with gparted, and if
it is not single partition Fat32, then make it so and try again
with the 'experimental' option.
If that doesn't do it, then give our experts here more details
and they'll get to the bottom of it.
Howie, another possibility.
See the following thread.
http://knoppix.net/forum/threads/303...light=reiserfs
There is an acknowledged blip in the experimental setup for some folks.
see especially post #21.
If that's your problem you can try the solution in that thread or wait for Knoppix 7.1.
That'll likely be late March or April even.
Basically, there are two ways to get out of the 4GB persistent store squeeze without going into "experimental" features. First, running Knoppix off a Poor Man's Install on a file system allowing >4GB files (NTFS, ext3/4 reiserfs...), and extending the persistent file. This may also be done on a USB stick, creating a smaller boot partition, putting Knoppix on a larger storage partition, and micro-remastering.
In my experience, if 4GB persistent store is really too little, it is in many cases way better to go by the second route: You mount extra volumes, either directly as partitions, or as loop-mounted images. I routinely setup a large storage partition on the main hard disk, mount it on /store, and use it for all sorts of storage except for programs and program data. If I have to use a Windows PC and cannot re-partition the main disk, I set up a large loop file and mount that image as /store.
You can also extend persistent store within the FAT32 limitation by adding volumes knoppix-data2.img, knoppix-data3.img etc in the KNOPPIX directory, and, for example, modify /etc/rc.local to mount them on boot. Those will be copied with the directory when you use the plain old knoppix-to-flash function.
